General Sensory Afferent Systems (GSA) Flashcards
Autonomous Zones: bottom of the paw (thoracic limb)
Median Nerve
___________: how nervous system receives information about the external environment
Enteroception: how nervous system receives information about the external environment
Autonomous Zones: Inner aspect of the pinna
Facial Nerve
Autonomous Zones: Inguinal area
Genitofemoral Nerve
Autonomous Zones: Shoulder area
Axillary Nerve
Autonomous Zones: Medial aspect of the thigh
Saphenous Nerve
___________: same sensory information is sent to multiple destinations for different purposes
Divergence: same sensory information is sent to multiple destinations for different purposes
__________: information traveling to the nervous system retains spacial relationships of the receptors in the periphery
Somatotopy: information traveling to the nervous system retains spacial relationships of the receptors in the periphery
__________: determine how sensitive an area is
Receptive Fields: determine how sensitive an area is
__________: sensory from skin and skeletal muscle
General Somatic Afferent (GSA): sensory from skin and skeletal muscle
____________: how nerveous system recieves information about the position and movement of the body
Proprioception: how nerveous system recieves information about the position and movement of the body
Explain the Somatosensory Pathway
Stimulus to Primary Neuron
Primary Neuron to Secondary Neuron
Secondary Neuron to Contralateral Thalamus
Somatosensory inputs go to the (ipsilateral/contralateral) thalamus/cortex
Somatosensory inputs go to the (ipsilateral/contralateral) thalamus/cortex
Afferent information can go where
Cortex
Cerebellum (Specific Spinal Cord Segments)
ARAS
Autonomous Zones: Mandible and back of the ear
Mandibular Branch of Trigeminal Nerve
Autonomous Zones: Caudal aspect of the thoracic limb (and 5th digit)
Ulnar Nerve
Autonomous Zones: Craniolateral aspect of the pelvic limb
Common Peronial (Fibular) Nerve
Increased receptor density in periphery is directly related with the amount of space in the __________ dedicated to sensation of that area.
Increased receptor density in periphery is directly related with the amount of space in the thalamus and cortex dedicated to sensation of that area.
___________: how the nervous system receives info about the internal environment (GVA)
Interoception: how the nervous system receives info about the internal environment (GVA)
Autonomous Zones: Caudomedial aspect of the pelvic limb, including the bottom of the paw.
Tibial Nerve
Autonomous Zones: Maxilla and temoporal regions
Maxillary branch of Trigeminal Nerve
The __________ is the relay and processing point for all conscious proprioception.
The thalamus/cortex is the relay and processing point for all conscious proprioception.
Autonomous Zones: Lateral thigh
Sciatic Nerve
__________: different aspects of the same sensory experience perceived at different parts of teh brain of at the same time.
Parallel Processing: different aspects of the same sensory experience perceived at different parts of teh brain of at the same time.
Autonomous Zones: Medial aspect of the brachium and antebrachium
Musculocutaneous Nerve
Autonomous Zones: Cranial aspect of the thoracic limb
Radial Nerve
Autonomous Zones: Medial Canthus of the eye
Opthalamic branch of Trigeminal Nerve
___________: sensory from the autonomic nervous system
General Visceral Afferent (GVA): sensory from the autonomic nervous system
